The use of a buffered string let the user review what they had typed before passing it to the program for processing. Up to six digits are read (as 65535 = 216 - 1 has ...
You have already created a plist. This plist will remain same in app. If you want to edit the data in this plist, add new data in plist or remove data from plist, you can't make changes in this file. For this purpose you will have to store your plist in Document Directory. You can edit your plist s...
Avoid this Anti-Pattern var myDeferred = $q.defer(); $http(config).then(function(res) { myDeferred.resolve(res); }, function(error) { myDeferred.reject(error); }); return myDeferred.promise; There is no need to manufacture a promise with $q.defer as the $http service alread...
This is just an extension on the sealed trait variant where a macro generates a set with all instances at compile time. This nicely omits the drawback that a developer can add a value to the enumeration but forget to add it to the allElements set. This variant especially becomes handy for large en...
For instance you have a bundle, which generated by the symfony console. In this case in the DependencyInjection/Configuration.php you have to insert your configuration representation: $treeBuilder = new TreeBuilder(); $rootNode = $treeBuilder->root('amazingservice'); $rootNod...

This technique relies on padding at the table cell level to structure the button, and both HTML attributes and CSS to style the button. No VML means simpler code, but no background images in Outlook. <table width="100%" border="0" cellspacing="0" cellpadding="0...
This technique relies on adding thick borders to the link itself to build the button's CTA. Using borders is universally understood by email clients, but limit button appearance solid colors. <table width="100%" border="0" cellspacing="0" cellpadding="0"&g...

There is a particular syntax that allow us to write cons cell in a more compact way than using the cons constructor. A pair can be written as such: '(1 . 2) == (cons 1 2) The big difference is that we can create pairs using quote. Otherwise, Scheme would create a proper list (1 . (2 . '())). T...
A enum declares a set of ordered values - the typedef just adds a handy name to this. The 1st element is 0 etc. typedef enum { Monday=1, Tuesday, Wednesday } WORKDAYS; WORKDAYS today = Monday;//value 1

Since every Applicative Functor is a Functor, fmap can always be used on it; thus the essence of Applicative is the pairing of carried contents, as well as the ability to create it: class Functor f => PairingFunctor f where funit :: f () -- create a context, carrying nothing ...
